Could you explain the Sweep skills please? I don't understand how actually they're useful.
I mean normally they really aren’t that useful.
The idea is that you give up your ability to do doubles, in exchange for able to hit a foe without retaliation. But you still have to meet speed requirements (+1 speed over the foes) in order for it to activate.
The idea originally was that a unit could hit incredibly hard without having to worry about their defences, kinda like OHKO the foe in one shot play. But in theory it kinda fell flat? Many units can speed creep each other and even then you want multiple hits for charges.
The main use for them though was found in dagger users, whose biggest weakness before was that they were oneshot by most units when trying to place a debuff, but with one of these sweep skills they can safely place debuffs on foes without worrying about their hp.
Hopefully that clears it up a little bit!
